Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
Index of this chapter:
2.1 Safety Instructions
2.2 Warnings
2.3 Notes
2.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains/AC Power via an isolation
transformer (> 800 VA).
•Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:
•Route the wire trees correctly and fix them with the
mounted cable clamps.
•Check the insulation of the Mains/AC Power lead for
external damage.
•Check the strain relief of the Mains/AC Power cord for
proper function.
•Check the electrical DC resistance between the Mains/AC
Power plug and the secondary side (only for sets that have
a Mains/AC Power isolated power supply):
1. Unplug the Mains/AC Power cord and connect a wire
between the two pins of the Mains/AC Power plug.
2. Set the Mains/AC Power switch to the "on" position
(keep the Mains/AC Power cord unplugged!).
3. Measure the resistance value between the pins of the
Mains/AC Power plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 Mohm and 12 Mohm.
4. Switch "off" the set, and remove the wire between the
two pins of the Mains/AC Power plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
2.2Warnings
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this same potential. Available
ESD protection equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
– Wristband tester 4822 344 13999.
•Be careful during measurements in the high voltage
section.
•Never replace modules or other components while the unit
is switched "on".
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
2.3Notes
2.3.1General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode (see chapter 5) with a colour bar
signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated
otherwise) and picture carrier at 475.25 MHz for PAL, or
61.25 MHz for NTSC (channel 3).
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
•The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
semiconductors in the unit, irrespective of the type
indication on these semiconductors.
•Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.
2.3.2Schematic Notes
•All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kohm).
•Resistor values with no multiplier may be indicated with
either an "E" or an "R" (e.g. 220E or 220R indicates 220
ohm).
•All capacitor values are given in micro-farads (µ= x10
nano-farads (n= x10
•Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
•An "asterisk" (*) indicates component usage varies. Refer
to the diversity tables for the correct values.
•The correct component values are listed in the Spare Parts
List. Therefore, always check this list when there is any
doubt.
2.3.3Rework on BGA (Ball Grid Array) ICs
General
Although (LF)BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB
and replacing it with a new component. If an (LF)BGA is
removed from a PWB, the solder balls of the component are
deformed drastically so the removed (LF)BGA has to be
discarded.
Device Removal
As is the case with any component that, is being removed, it is
essential when removing an (LF)BGA, that the board, tracks,
solder lands, or surrounding components are not damaged. To
remove an (LF)BGA, the board must be uniformly heated to a
temperature close to the reflow soldering temperature. A
uniform temperature reduces the risk of warping the PWB.
To do this, we recommend that the board is heated until it is
certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the
appropriate temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has been shown to
result in problems during re-soldering.

),
).
Safety Instructions, Warnings, and Notes
EN 9FJ3.0E LA2.
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be
aligned under a microscope or magnifying glass. If this is not
possible, try to align the (LF)BGA with any board markers.
So as not to damage neighbouring components, it may be
necessary to reduce some temperatures and times.
More Information
For more information on how to handle BGA devices, visit this

not available for all regions). After login, select “Magazine”,
then go to “Repair downloads”. Here you will find Information
on how to deal with BGA-ICs.
2.3.4Lead-free Solder
Philips CE is producing lead-free sets (PBF) from 1.1.2005
onwards.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 5 and 6 refer to the production year, digits
7 and 8 refer to production week (in example below it is 1991
week 18).
E_06532_024.eps
230205
avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
•Use only original spare-parts listed in the Service-Manuals.
Not listed standard material (commodities) has to be
purchased at external companies.
•Special information for lead-free BGA ICs: these ICs will be
delivered in so-called "dry-packaging" to protect the IC
against moisture. This packaging may only be opened
shortly before it is used (soldered). Otherwise the body of
the IC gets "wet" inside and during the heating time the
structure of the IC will be destroyed due to high (steam-)
pressure inside the body. If the packaging was opened
before usage, the IC has to be heated up for some hours
(around 90°C) for drying (think of ESD-protection!).
Do not re-use BGAs at all!
•For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:
•Always use the highest temperature to solder, when using
SAC305 (see also instructions below).
•De-solder thoroughly (clean solder joints to avoid mix of
two alloys).
Caution: For BGA-ICs, you must use the correct temperatureprofile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions)
You will find this and more technical information within the
"Magazine", chapter "Repair downloads".
For additional questions please contact your local repair help
desk.
Figure 2-1 Serial number example
Regardless of the special lead-free logo (which is not always
indicated), one must treat all sets from this date onwards
according to the rules as described below.
P
b
Figure 2-2 Lead-free logo
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder paste is required,
please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
•Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilise the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
•Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilised at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to
2.3.5Alternative BOM identification
In September 2003, Philips CE introduced a change in the way
the serial number (or production number, see Figure 2-1) is
composed. From this date on, the third digit in the serial
number (example: AG2B0335000001) indicates the number of
the alternative BOM (Bill of Materials used for producing the
specific model of TV set). It is possible that the same TV model
on the market is produced with e.g. two different types of
displays, coming from two different O.E.M.s.
By looking at the third digit of the serial number, the service
technician can see if there is more than one type of B.O.M.
used in the production of the TV set he is working with. He can
then consult the At Your Service Web site, where he can type
in the Commercial Type Version Number of the TV set (e.g.
28PW9515/12), after which a screen will appear that gives
information about the number of alternative B.O.M.s used.
If the third digit of the serial number contains the number 1
(example: AG1B033500001), then there is only one B.O.M.
version of the TV set on the market. If the third digit is a 2
(example: AG2B0335000001), then there are two different
B.O.M.s. Information about this is important for ordering
the correct spare parts!
For the third digit, the numbers 1...9 and the characters A...Z
can be used, so in total: 9 plus 26 = 35 different B.O.M.s can
be indicated by the third digit of the serial number.
2.3.6Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
•Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

5.7 Protections
5.8 Fault Finding and Repair Tips
5.9 Software Upgrading
5.1Test Points
The chassis is equipped with test points (Fxxx) printed on the
circuit board assemblies. As most signals are digital, it will be
difficult to measure waveforms with a standard oscilloscope.
Several key ICs are capable of generating test patterns, which
can be controlled via ComPair. In this way it is possible to
determine which part is defective.
Perform measurements under the following conditions:
•Service Default Mode.
•Video: Colour bar signal.
•Audio: 3 kHz left, 1 kHz right.
5.2Service Modes
Service Default mode (SDM) and Service Alignment Mode
(SAM) offers several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").
•All service-unfriendly modes (if present) are disabled, like:
– (Sleep) timer.
– Child/parental lock.
– Picture mute (blue mute or black mute).
– Automatic volume levelling (AVL).
– Auto switch "off" (when no video signal was received
for 10 minutes).
– Skip/blank of non-favourite pre-sets.
– Smart modes.
– Auto store of personal presets.
– Auto user menu time-out.
How to Activate SDM
For DVBT TV’s there are two kinds of SDM : an analogue SDM
and a digital SDM. Tuning will happen according table “SDM
Default Settings”.
•Analogue SDM: use the standard RC-transmitter and key
in the code “062596”, directly followed by the “MENU”
button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it "off", push the “MENU”
button again.
•Digital SDM: use the standard RC-transmitter and key in
the code “062593”, directly followed by the “MENU” button.
Depending on the software version it is possible that the
tuning will not work correctly.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it "off", push the “MENU”
button again.
•Analogue SDM can also be activated by shorting for a
moment the two solder pads [1] on the SSB, with the
indication “SDM”. They are located outside the shielding.
Activation can be performed in all modes, except when the
set has a problem with the Stand-by Processor. See figure
“Service mode pads”.
SDM
SDM
11
5.2.1Service Default Mode (SDM)
Purpose
•To create a pre-defined setting, to get the same
measurement results as given in this manual.
•To override SW protections detected by stand-by
processor and make the TV start up to the step just before
protection (a sort of automatic stepwise start up). See
paragraph “Stepwise Start Up”.
•To override SW protections detected by Viper. Depending
on the SW version it is possible that this mechanism does
not work correctly. See also paragraph “Error codes”.
•To start the blinking LED procedure (not valid in protection
mode).

After activating this mode, “SDM” will appear in the upper right
corner of the screen (if you have picture).
How to Navigate
When you press the “MENU” button on the RC transmitter, the
set will toggle between the SDM and the normal user menu
(with the SDM mode still active in the background).
How to Exit SDM
Use one of the following methods:
•Switch the set to STAND-BY via the RC-transmitter.
Service Modes, Error Codes, and Fault Finding
EN 27FJ3.0E LA5.
•Via a standard customer RC-transmitter: key in “00”sequence.
5.2.2Service Alignment Mode (SAM)
Purpose
•To perform (software) alignments.
•To change option settings.
•To easily identify the used software version.
•To view operation hours.
•To display (or clear) the error code buffer.
How to Activate SAM
Via a standard RC transmitter: key in the code “062596”
directly followed by the “INFO” button. After activating SAM
with this method a service warning will appear on the screen,
you can continue by pressing the red button on the RC.
Contents of SAM:
•Hardware Info.
– A. SW Version. Displays the software version of the
VIPER software (main software) (example: JA30E-
1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN).
•AAAA= the software name.
•B= the region: A= AP, E= EU, L= LatAm, U = US.
For AP sets it is possible that the Europe software
version is used.
•X.Y.W.Z= the software version, where X is the
main version number (different numbers are not
compatible with one another) and Y.W.Z is the sub
version number (a higher number is always
compatible with a lower number).
•NNNNN= last five digits of 12nc code of the
software.
– B. SBY PROC Version. Displays the software version
of the stand-by processor.
– C. Production Code. Displays the production code of
the TV, this is the serial number as printed on the back
of the TV set. Note that if an NVM is replaced or is
initialized after corruption, this production code has to
be re-written to NVM. ComPair will foresee in a
possibility to do this.
•Operation Hours. Displays the accumulated total of
operation hours (not the stand-by hours). Every time the
TV is switched "on/off", 0.5 hours is added to this number.
•Errors. (Followed by maximal 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see paragraph “Error Codes”).
•Defective Module. Here the module that generates the
error is displayed. If there are multiple errors in the buffer,
which are not all generated by a single module, there is
probably another defect. It will then display the message
“UNKNOWN” here. Not all errors will display a defective
module name.
•Reset Error Buffer. When you press “cursor right” and
then the “OK” button, the error buffer is reset.
•Alignments. This will activate the “ALIGNMENTS” submenu.
•Dealer Options. Extra features for the dealers.
•Options. Extra features for Service. For more info
regarding option codes, see chapter 8.
Note that if you change the option code numbers, you have
to confirm your changes with the “OK” button before you
store the options. Otherwise you will lose your changes.
•Initialise NVM. When an NVM was corrupted (or replaced)
in the former EMG based chassis, the microprocessor
replaces the content with default data (to assure that the
set can operate). However, all preferences and alignment
values are gone now, and option numbers are not correct.
Therefore, this was a very drastic way. In this chassis, the
procedure is implemented in another way: The moment the
processor recognizes a corrupted NVM, the “initialize
NVM” line will be highlighted. Now, you can do two things
(depending of the service instructions at that moment):
– Save the content of the NVM via ComPair for
development analysis, before initializing. This will give
the Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialize the NVM (same as in the past, however now it
happens conscious).
Note: When you have a corrupted NVM, or you have replaced
the NVM, there is a high possibility that you will not have picture
any more because your display option is not correct. So, before
you can initialize your NVM via the SAM, you need to have
picture and therefore you need the correct display option. To
adapt this option, you can use ComPair (the correct HEX
values for the options can be found in the table below) or a
method via a standard RC (described below).
Changing the display option via a standard RC:
Key in the code “062598” directly followed by the “MENU”
button and “XXX” (where XXX is the 3 digit decimal display
option code as mentioned in the first column of the next table).
Make sure to key in all three digits, also the leading zero’s.
If the above action is successful, the front LED will go out as an
indication that the RC sequence was correct.
After the display option is changed in the NVM, the TV will go
to the Stand-by mode.
If the NVM was corrupted or empty before this action, it will be
initialised first (loaded with default values). This initialising can
take up to 20 seconds.

5.2.3Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Customer Helpdesk. The service
technician can then ask the customer to activate the CSM, in
order to identify the status of the set. Now, the service
technician can judge the severity of the complaint. In many
cases, he can advise the customer how to solve the problem,
or he can decide if it is necessary to visit the customer.
The CSM is a read only mode; therefore, modifications in this
mode are not possible.
When in this chassis, CSM is activated, a colour bar test
pattern will be visible for 5 seconds. This test pattern is
generated by the Pacific3. So if you see this test pattern you
can determine that the back end video chain (Pacific3, LVDS
and display) is working.
Also new in this chassis: when you activate CSM and there is
a USB stick connected to the TV, the software will dump the
complete CSM content to the USB stick. The file (Csm.txt) will
be saved in the root of your USB stick. This info can be handy
if you don’t have picture.
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
•Operating hours. Here you are able to reset
the operations hours of the display. This has to be done in
case of replacement of the display.
•Upload to USB. Here you are able to upload several
settings from the TV to a USB stick which is connected to
the Side IO. The four items are “Channel list”, “Personal
settings”, “Option codes” and “Display-related alignments”.
First you have to create a directory “repair\” in the root of
the USB stick.To upload the settings you have to select
each item separately, press “cursor right”, confirm with
“OK” and wait until “Done” appears. Now the settings are
stored onto your USB stick and can be used to download
onto another TV or other SSB. Uploading is of course only
possible if the software is running and if you have picture.
This method is created to be able to save the customer’s
TV settings and to store them into another SSB.
•Download from USB. Here you are able to download
several settings from the USB stick to the TV. Same way of
working as with uploading. To make sure that the download
of the channel list from USB to the TV is executed properly,
it is necessary to restart the TV and tune to a valid preset if
necessary.
How to Navigate
•In SAM, you can select the menu items with the “CURSOR
UP/DOWN” key on the RC-transmitter. The selected item
will be highlighted. When not all menu items fit on the
screen, move the “CURSOR UP/DOWN” key to display the
next/previous menu items.
•With the “CURSOR LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.
•With the “OK” key, it is possible to activate the selected
action.
How to Exit SAM
Use one of the following methods:
•Press the “MENU” button on the RC-transmitter.
•Switch the set to STAND-BY via the RC-transmitter.
How to Navigate
By means of the “CURSOR-DOWN/UP” knob on the RCtransmitter, you can navigate through the menus.
Contents of CSM
•Set Type. This information is very helpful for a helpdesk/
workshop as reference for further diagnosis. In this way, it
is not necessary for the customer to look at the rear of the
TV-set. Note that if an NVM is replaced or is initialized after
corruption, this set type has to be re-written to NVM.
ComPair will foresee a possibility to do this.
•Production Code. Displays the production code (the serial
number) of the TV. Note that if an NVM is replaced or is
initialized after corruption, this production code has to be
re-written to NVM. ComPair will foresee a possibility to do
this.
•Code 1. Gives the latest five errors of the error buffer. As
soon as the built-in diagnose software has detected an
error the buffer is adapted. The last occurred error is
displayed on the leftmost position. Each error code is
displayed as a 2-digit number. When less than 10 errors
occur, the rest of the buffer is empty (00). See also
paragraph Error Codes for a description.
•Code 2. Gives the first five errors of the error buffer. See
also paragraph Error Codes for a description.
•Options 1. Gives the option codes of option group 1 as set
in SAM (Service Alignment Mode).
•Options 2. Gives the option codes of option group 2 as set
in SAM (Service Alignment Mode).
•12NC SSB. Gives an identification of the SSB as stored in
NVM. Note that if an NVM is replaced or is initialized after
corruption, this identification number has to be re-written to
NVM. ComPair will foresee a possibility to do this.
This identification number consists of 14 characters and is
built up as follows:
- 8 last characters of the 12NC of the SSB itself.
- the serial number of the SSB, which consists of 6 digits.
Both can be found on a sticker on the PWB of the SSB itself
(not on the sticker on the outside of the shielding!). The
format of the identification number is then as follows:
<last 8 characters of 12NC of SSB><serial number of
SSB> (total 14 characters).
•Digital Natural Motion. Gives the last status of the Digital
Natural Motion setting, as set by the customer. Possible
Service Modes, Error Codes, and Fault Finding

and “Maximum”. See DFU on how to change this item.
•Noise Figure. Gives the noise ratio for the selected
transmitter. This value can vary from 0 (good signal) to 127
(average signal) and to 255 (bad signal). For some
software versions, the noise figure will only be valid when
“Active Control” is set to “medium” or “maximum” before
activating CSM. Noise figure is not applicable for DVBT
channels.
•Headphone Volume. Gives the last status of the
headphone volume, as set by the customer. The value can
vary from 0 (volume is minimum) to 100 (volume is
maximum). See DFU on how to change this item.
•Dolby. Indicates whether the received transmitter
transmits Dolby sound (“ON”) or not (“OFF”). Attention: The
presence of Dolby can only be tested by the software on
the Dolby Signalling bit. If a Dolby transmission is received
without a Dolby Signalling bit, this indicator will show “OFF”
even though a Dolby transmission is received.
•Surround Mode. Indicates the by the customer selected
sound mode (or automatically chosen mode). Possible
values are “STEREO” and “VIRTUAL DOLBY
SURROUND”. It can also have been selected
automatically by signalling bits (internal software). See
DFU on how to change this item.

5.2.4Service Mode of Converter Boards for Ambi Light
Purpose
To switch on the lamps manually in case I
fails.
The Service Mode can be activated by disconnecting
connectors 1M59 and 1M49 and then by shorting for a moment
the two solder pads [1] on the Ambi Light Inverter Panel. See
figure “Service Mode pads”.

Repair Tips
In case only one or no lamp unit at all works, probably the
+12Vb (12 - 13 V) is not available or the fuse is broken. Check
for broken MOSFETS or check if they are switched off properly
by the transistors connected to the PWM outputs of the
microprocessor.

G_15950_049.eps
Figure 5-2 Service Mode pads AmbiLight panel
In this chassis, both single and double fitted boards can be
used. The double fitted boards are used in sets with 3 or 4
sided Ambi Light units whereas the single fitted boards are
used in sets with 2 sided Ambi Light units. A double fitted board
can drive 2 lamp units (6 lamps) and a single fitted board can
drive 1 lamp unit (3 lamps).
The double fitted boards are supplied by +12Va and +12Vb.
The microprocessor is supplied by +12Va.
Therefore, if only +12Va is available, lamp unit B will not work.

In case the Ambi Light switches off after two seconds, serial
arcing or parallel arcing protection is active. Serial arcing
protection can be excluded by disconnecting the opto-coupler;
check for bad solder joints on transformer or lamp units.
Parallel arcing protection can be disabled by grounding pin 8 of
the microprocessor. Usually the switching frequency (normally
63 kHz) will then be too high. Possible causes are one
MOSFET of the converter has no gate drive or is broken, or
there is a short-circuit of the output of the transformer.
5.3Stepwise Start-up
The stepwise start-up method, as known from FTL/FTP sets
(EMG based sets) is not valid any more. There are two possible
situation: one for protections detected by standby software and
one for protections detected by main software.
When the TV is in a protection state due to an error detected by
standby software (and thus blinking an error) and SDM is
activated via shortcutting the pins on the SSB, the TV starts up
until it reaches the situation just before protection. So, this is a
kind of automatic stepwise start-up. In combination with the
start-up diagrams below, you can see which supplies are
present at a certain moment. Important to know here is, that if
e.g. the 3V3 detection fails (and thus error 11 is blinking) and
the TV is restarted via SDM, the Stand-by Processor will
enable the 3V3, but will not go to protection now. The TV will
stay in this situation until it is reset (Mains/AC Power supply
interrupted).
When the TV is in protection state due to an error detected by
main software (Viper protection) and SDM is activated via
shortcutting the pins on the SSB, the TV starts up and ignores
the error. Due to architectural reasons it is possible that the TV
will end up in an undefined state (e.g. when the fast I
blocked). In this case diagnose has to be done via ComPair.
The abbreviations “SP” and “MP” in the figures stand for:
•SP: protection or error detected by the Stand-by Processor.
•MP: protection or error detected by the VIPER Main Processor.
In the next transition diagrams for “POD” should be read
“Common Interface (CI)”. For analogue sets, any reference to
“POD” should be neglected.

C bus is
Figure 5-3 Building blocks of Converter Board
The microprocessor performs the following tasks:
•Dimming of Ambi Light by means of PWM.
•Translation of I
2
C-bus commands to PWM.
•Switches the Ambi Light board to protection if needed (in
case of protection only the lamps switch off, no set
protection is triggered).
There are two ways of protection: parallel arcing protection and
serial arcing protection.
Parallel arcing protection is performed by sensing the switching
frequency. In case of short circuit of the transformer output, this
frequency > 100 kHz and the board goes into protection.
Serial arcing protection is performed by detection of arc in
ground wire of the lamp units. In this case, the protection pulse
is transmitted via an opto-coupler.
Protection can be disabled by short-circuiting diode 6112 or
capacitor 2173 or by connecting pin 8 of the microprocessor to
ground.
